at A and B, both being identical to each other.

My invention relates to improvements in adjustable furniture, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.

An object of my invention is to provide adjustable furniture designed to be used in printing offices. Up to the present time, type or plates have been locked in a chase by furniture, i. e. small. pieces of wood, and quoins. Considerable difficulty is experienced in looking the cut in place if the cut is secured in a chase on a bias. A number of pieces of furniture have to be cut in different sizes and lengths in order to have these contact with the inclined sides of-the cut. 7

The principal object of my invention is to provide an adjustable piece of furniture which has two opposed edges that may be swung at an angle with respect to each other so that one edge can engage with the out while the other contacts the furniture or the side of the chase.

A further object of my invention is to provide a device of the type described which is extremely simple in construction and which consists of two pieces identical in shape and designed so that they will interlock with each other when placed in the chase. v Other objects and advantages will appear as the specification proceeds, the novel features will be particularly pointed out in What I hereinafter claim.

My invention is illustrated in the accom panying drawing forming a part of this application, in which Figure 1 is a .top plan view of a chase showing furniture, quoins and a cut disposed therein, and also showing a numberof the adjustable pieces of furniture disposed in position; a I

Figure 2 is a top plan view of the device;

Figure 3 is a section along the line 33 of Figure 2; I

Figure 4 is a section along the line 4.-4= of .Figure 2; and

Figure 5 is a perspective View of one of the members forming the device.

In carrying out my invention, I provide two identical members indicated generally A description of one will therefore sufiice.

The member B has a central circularshaped portion land a base 2. The portion 1 is one-half the thickness of the base 2, and the portion "isprovided with a bevelled edge 3 that extends through an arcof 180. The base 2has recesses 4: and 5 cut therein, these recesses having edges 6 and 7 that'are of the same height as the width of the portion 1.

The member B has a bevelled groove 8 cut therein in the base 2 for receiving the bevelled edge 3 of the member A; j The base is pro vided with curved edges 9 and 10 and a curved edge 11 that coincides with the curved portion 1 of the member A. The bevelled groove'is out into the curved edge 11. j a Figure 5shows a perspective view of the member B. It will be noted from this figure that the portion 1 projects from the base 2 and then .the' surface 12.,of the portion 1 contacts with asimilar surface of the member A. This figure further shows the curved edges 9 and 10 and the curved edge 11, the latter having the bevelled groove 8 out therein.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

The two members are placed one on top of the other as shown in Figure 2, and Figure 3 shows how. the bevelled edges 3 of each member enter the bevelled grooves 8. The edges and grooves are portions of circles, and therefore the member A may be swung with respect to the member B into various positions as shown in Figure 1. The recesses 4 and 5 permil; the member to be swung into rather ex-. treme angles.

Assume that a cut indicated at 13 in Figure 1 is to be placed on a'bias in a chase 14. Furniture indicated generally at 15 isbuilt up in the manner shown, and then my adj ustable furniture is placed at the points 0, D.

and E for contacting with the inclined edges of the cut. Theedges 16 of the bases 2 contact with the sides of the cut and with the furniture. 'Quoins 17 are used for tighten ing up thefurniture, and these 'quoins will cause the adjustable furniture to contact with the cut and hold it in positions its Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes, and I reserve the right to employ such changes as may come within the scope of the invention as claimed.

I claim:

1. An adjustable furniture comprising two identical members pivotally secured to each other, the outer edges of said members being swingable into various angular positions with respect to each other.

2. An adjustable furniture comprising two identical members, each member having a circular portion and a circular groove for receiving the portion of the other member.

3. An adjustable furniture comprising two identical members, each member having a circular portion and a circular groove for receiving the portion of the other member, the edges of said portions being bevelled and the grooves being bevelled for causing the members to interlock with each other.

4. An adjustable furniture comprising two identical members, each member having a circular portion with a bevelled edge and a base portion, each base portion having a bevelled groove for receiving the bevelled edge of the other member.

5. An adjustable furniture comprising two identical members, each member having an arcuate portion rotatable on the other portion for permitting the opposed edges to swing into various angular positions, the thickness of the combined members remaining the same throughout all adjustments.
